4-Set Soil Moisture Detection Sensor with Probe DC 3.3-12V Digital and Analog Signal Output Compatible with Raspberry Pi (1.3m Cable/4.27ft)

Name: Soil Moisture Sensor Size: 36x15x7mm(1.42*0.6*0.28in) Voltage: 3.3-12VDC Current: Working current<20mA;The output current <30mA Interface: + – DO AO,DO digital/AO analog Directions of use: 1. [+] connect to the positive pole of the power supply; [-] connect the negative pole of the power supply; Do not reverse the connection, otherwise it may burn out Chip. When the power is connected, the [P] power indicator lights up. The module is working properly. 2. The blue potentiometer can be adjusted clockwise/counterclockwise, which can increase/decrease the detection sensitivity of the probe, taking the "thermal sensor" as an example, assuming that the default is triggered at 25degC, and the [DO] output is valid at a low level. After clockwise adjustment, the temperature can be triggered when the temperature is below 25degC. Counterclockwise is triggered above 25degC. 3. When the potentiometer is adjusted clockwise to the output indicator light of [S], it means that the adjustment range has exceeded the test threshold, and when it is adjusted counterclockwise to the point that it cannot be adjusted, the threshold value is exceeded. When adjusting, the threshold value cannot be exceeded, otherwise it cannot be used normally. Potentiometer adjustment is only used for the [DO] port and is not related to the [AO] output. 4. The output of [AO] is analog (voltage), which can be directly detected by the AD port of the single-chip microcomputer.

Features

• Four Soil Moisture Sensors with Corrosion-Resistant Probes:This set includes four soil moisture sensors, each equipped with a durable, corrosion-resistant probe and a 1.3m (4.27ft) cable;The sensor dimensions are 36mm (L) x 15mm (W) x 7mm (H) (1.42in x 0.6in x 0.28in), making them compact and ideal for various gardening and monitoring projects
• Wide Voltage Range and Multiple Outputs:Operating on a voltage range of 3.3-12VDC with a low current draw (<20mA), the sensor features two output options: digital output (DO) and analog output (A0);These outputs are ideal for integration with microcontrollers like Arduino and Raspberry Pi, providing flexibility in your projects
• Accurate Soil Moisture Detection:The probe detects soil moisture levels, and the voltage comparator determines the moisture state;When moisture exceeds the preset threshold, the DO output goes low, providing a clear indication of soil wetness, making this sensor perfect for automation and precision irrigation systems
• Adjustable Sensitivity for Precise Control:Equipped with a blue potentiometer for sensitivity adjustment, this feature allows you to fine-tune the DO output based on your project needs;The A0 analog output remains unaffected by sensitivity adjustments, ensuring consistent analog signal readings for accurate soil moisture analysis
• Long-Lasting and Fast-Responding Probe:Designed with a corrosion-resistant probe, this sensor ensures reliable performance for at least six months, offering quick response times and high accuracy,it is ideal for continuous soil moisture monitoring
